Update the playback speed of the test data. This will iterate over all the editor actors, check whether they are test mode actors, and if so it will update the play speed. For example a linear skinned mesh will update its skeletal mesh component's play speed, while a geometry cache ground truth actor would update the play speed set on the geometry cache component.
